The Fund invests primarily in equity securities but may also invest in debt securities including U.S. Treasury and agency bonds and notes.<br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In complying with the 80% investment requirement, the Fund may include synthetic securities that have economic characteristics similar to the Fund&#146;s direct investments that are counted toward the 80% investment requirement. <br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Fund considers an issuer to be a real estate or real estate-related issuer if at least 50% of its assets, gross income or net profits are attributable to ownership, construction, management or sale of residential, commercial or industrial real estate. These companies include (i)&#160;real estate investment trusts (REITs) or other real estate operating companies that (a)&#160;own property, (b)&#160;make or invest in short term construction and development mortgage loans, or (c)&#160;invest in long-term mortgages or mortgage pools, and (ii)&#160;companies whose products and services are related to the real estate industry, such as manufacturers and distributors of building supplies and financial institutions that issue or service mortgages. <br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Fund may invest in equity and debt securities of companies unrelated to the real estate industry that the portfolio managers believe are undervalued and have potential for growth of capital. The Fund limits its investments in debt securities unrelated to the real estate industry to those that are investment-grade or deemed by the Fund&#146;s portfolio managers to be of comparable quality. <br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Fund invests, under normal circumstances, in issuers located in at least three different countries, including the U.S. As of February&#160;29, 2012, the principal countries in which the Fund invested were the United States, Hong Kong, Japan, Australia and the United Kingdom. <br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Fund may invest in non-investment grade debt securities (commonly known as &#147;junk bonds&#148;) of real estate and real estate-related issuers. <br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Fund may engage in short sales of securities. A short sale occurs when the Fund sells a security, but does not deliver a security it owns when the sale settles. Instead, it borrows that security for delivery when the sale settles. The Fund may engage in short sales with respect to securities it owns (short sales against the box) or securities it does not own. Generally, the Fund will sell a security short to (1)&#160;take advantage of an expected decline in the security price in anticipation of purchasing the same security at a later date at a lower price, or (2)&#160;to protect a profit in a security that it owns (short sales against the box). The Fund will not sell a security short if, as a result of such short sale, the aggregate market value of all securities sold short exceeds 10% of the Fund&#146;s net assets. <br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;When constructing the portfolio, the portfolio managers use a fundamentals-driven investment process, including an evaluation of factors such as real property market cycle analysis, real property evaluation and management and structure review to identify securities with characteristics including (i)&#160;quality underlying properties, (ii)&#160;solid management teams with the ability to effectively manage capital structure decisions, and (iii)&#160;attractive valuations relative to peer investment alternatives. The portfolio managers and investment team focus on equity REITs and real estate operating issuers. Some of the fundamental factors that are evaluated in screening potential investments for the Fund include: forecasted occupancy and rental rates of the various property markets in which a firm may operate, property locations, physical attributes and cash flow generating capacity of an issuer&#146;s properties and calculating relative return potential, asset quality, management depth and skill, insider ownership, overall debt levels, percentage of variable rate financing and fixed charge coverage ratios. The issuers that are believed to have the most attractive fundamental attributes are then screened according to pricing factors that allow the management team to assess security valuations relative to one another and relative to the investment teams&#146; assessment of underlying asset value. The portfolio managers also consider the relative liquidity of each security in the construction of the Fund. The portfolio managers seek to construct a portfolio with risk characteristics similar to the FTSE EPRA/NAREIT Developed Real Estate Index (the benchmark index). The Fund seeks to limit risk through various controls, such as diversifying the portfolio property types and geographic areas as well as by limiting the size of any one holding. Various factors may lead to overweighting or underweighting of particular property types and/or geographic areas from time to time.<br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The portfolio managers will consider selling a security if they conclude (1)&#160;its relative valuation falls below desired levels, (2)&#160;its risk/return profile changes significantly, (3)&#160;its fundamentals change, or (4)&#160;a more attractive investment opportunity is identified.As with any mutual fund investment, loss of money is a risk of investing. An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency. The risks associated with an investment in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are:<br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Concentration Risk</i>. To the extent the Fund invests a greater amount in any one sector or industry, the Fund&#146;s performance will depend to a greater extent on the overall condition of the sector or industry, and there is increased risk to the Fund if conditions adversely affect that sector or industry. <br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Credit Risk</i>. The issuer of instruments in which the Fund invests may be unable to meet interest <font style="white-space: nowrap">and/or</font> principal payments, thereby causing its instruments to decrease in value and lowering the issuer&#146;s credit rating. <br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Foreign Securities Risk</i>. The Fund&#146;s foreign investments may be affected by changes in a foreign country&#146;s exchange rates, political and social instability, changes in economic or taxation policies, difficulties when enforcing obligations, decreased liquidity, and increased volatility. Foreign companies may be subject to less regulation resulting in less publicly available information about the companies. <br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>High Yield Bond (Junk Bond) Risk</i>. Junk bonds involve a greater risk of default or price changes due to changes in the credit quality of the issuer. The values of junk bonds fluctuate more than those of high-quality bonds in response to company, political, regulatory or economic developments. Values of junk bonds can decline significantly over short periods of time. <br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Interest Rate Risk</i>. Interest rate risk refers to the risk that bond prices generally fall as interest rates rise; conversely, bond prices generally rise as interest rates fall. Specific bonds differ in their sensitivity to changes in interest rates depending on their individual characteristics, including duration. <br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Management Risk</i>. The investment techniques and risk analysis used by the Fund&#146;s portfolio managers may not produce the desired results. <br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Market Risk</i>. The prices of and the income generated by the Fund&#146;s securities may decline in response to, among other things, investor sentiment, general economic and market conditions, regional or global instability, and currency and interest rate fluctuations. <br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>REIT Risk/Real Estate Risk</i>. Investments in real estate related instruments may be affected by economic, legal, cultural, environmental or technological factors that affect property values, rents or occupancies of real estate related to the Fund&#146;s holdings. Real estate companies, including REITs or similar structures, tend to be small and mid cap companies, and their shares may be more volatile and less liquid. The value of investments in real estate related companies may be affected by the quality of management, the ability to repay loans, the utilization of leverage and financial covenants related thereto, whether the company carries adequate insurance and environmental factors. If a real estate related company defaults, the Fund may own real estate directly, which involves the following additional risks: environmental liabilities, difficulty in valuing and selling the real estate, and economic or regulatory changes. <br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Short Sales Risk</i>. Short sales may cause the Fund to repurchase a security at a higher price, causing a loss. As there is no limit on how much the price of the security can increase, the Fund&#146;s exposure is unlimited. <br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Synthetic Securities Risk</i>. Fluctuations in the values of synthetic securities may not correlate perfectly with the instruments they are designed to replicate. Synthetic securities may be subject to interest rate changes, market price fluctuations, counterparty risk and liquidity risk. <br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>U.S.&#160;Government Obligations Risk</i>. The Fund may invest in obligations issued by U.S.&#160;Government agencies and instrumentalities that may receive varying levels of support from the government, which could affect the Fund&#146;s ability to recover should they default.As with any mutual fund investment, loss of money is a risk of investing.After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes.Actual after-tax returns depend on an investor&#146;s tax situation and may differ from those shown, and after-tax returns shown are not relevant to investors who hold their Fund shares&#160;through tax-deferred arrangement, such as 401(k) plans or individual retirement accounts.000.00910.0088230199290281<b>Portfolio Turnover.</b>-0.4468-0.06512009-06-300.2988Worst Quarter2008-12-31The Fund invests primarily in equity securities of mid-capitalization issuers. <br/><br/>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; The Fund may invest up to 25% of its total assets in foreign securities. <br/><br/>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; The Fund considers an issuer to be a mid-capitalization issuer if it has a market capitalization, at the time of purchase, within the range of the largest and smallest capitalized issuers included in the Russell Midcap<sup style="FONT-SIZE: 85%; VERTICAL-ALIGN: text-top">&#174;</sup> Growth Index during the most recent <font style="WHITE-SPACE: nowrap">11-month</font> period (based on month-end data) plus the most recent data during the current month.

To narrow the investment universe, the Adviser uses a holistic approach that emphasizes fundamental research and, to a lesser extent, includes quantitative analysis. The Adviser then closely examines company fundamentals, including detailed modeling of all of a company&#8217;s financial statements and discussions with company management teams, suppliers, distributors, competitors, and customers. The Adviser uses a variety of valuation techniques based on the company in question, the industry in which the company operates, the stage of the business cycle, and other factors that best reflect a company&#8217;s value. The Adviser seeks to invest in companies with solid management teams, sound business models, strong financial health, attractive growth outlooks, and compelling valuations levels. <br/><br/> &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; The Adviser considers whether to sell a particular security when a company hits the price target, a company&#8217;s fundamentals deteriorate, or the catalysts for growth are no longer present or reflected in the stock price.<br/><br/>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; In attempting to meet its investment objective, the Fund engages in active and frequent trading of portfolio securities.-0.0651-0.0408-0.0709-0.0709-0.0554-0.0582-0.069As with any mutual fund investment, loss of money is a risk of investing. An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency. The risks associated with an investment in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are: <br/><br/>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <i>Active Trading Risk</i>. The Fund engages in frequent trading of portfolio securities. Active trading results in added expenses and may result in a lower return and increased tax liability.<br/><br/> &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <i>Foreign Securities Risk</i>. The Fund&#8217;s foreign investments may be affected by changes in a foreign country&#8217;s exchange rates, political and social instability, changes in economic or taxation policies, difficulties when enforcing obligations, decreased liquidity, and increased volatility. Foreign companies may be subject to less regulation resulting in less publicly available information about the companies. <br/><br/> &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <i>Growth Investing Risk</i>. Growth stocks tend to be more expensive relative to their earnings or assets compared with other types of stock. As a result they tend to be more sensitive to changes in their earnings and can be more volatile.<br/><br/> &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <i>Management Risk</i>. The investment techniques and risk analysis used by the Fund&#8217;s portfolio managers may not produce the desired results.<br/><br/>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <i>Market Risk</i>. The prices of and the income generated by the Fund&#8217;s securities may decline in response to, among other things, investor sentiment, general economic and market conditions, regional or global instability, and currency and interest rate fluctuations.<br/><br/>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <i>Small- and Mid-Capitalization Risks</i>. Stocks of small and mid-sized companies tend to be more vulnerable to adverse developments and may have little or no operating history or track record of success, and limited product lines, markets, management and financial resources. The securities of small and mid-sized companies may be more volatile due to less market interest and less publicly available information about the issuer. They also may be illiquid or restricted as to resale, or may trade less frequently and in smaller volumes, all of which may cause difficulty when establishing or closing a position at a desirable price.As with any mutual fund investment, loss of money is a risk of investing.<b><font style="font-family: Arial, Helvetica; color: #1E1C77">Investment Objective(s)</font></b><b><font style="font-family: Arial, Helvetica; color: #1E1C77">Fees and Expenses of the Fund</font></b><b>Portfolio Turnover.</b>2009-09-300.2045Worst Quarter2008-12-31The Fund invests under normal circumstances at least 80% of its net assets (plus any borrowings for investment purposes) in debt securities that are determined to be below investment grade quality. <br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In complying with the 80% investment requirement, the Fund may include synthetic securities that have economic characteristics similar to the Fund&#146;s direct investments that are counted toward the 80% investment requirement. <br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Fund considers debt securities to be below investment grade quality if they are rated BB/Ba or lower by Standard&#160;&#038; Poor&#146;s Ratings Services, Moody&#146;s Investors Service, Inc., or any other nationally recognized statistical rating organization (NRSRO), or are determined by the portfolio managers to be of comparable quality to such rated securities. These types of securities are commonly known as &#147;junk bonds.&#148; The Fund will principally invest in junk bonds rated B or above by an NRSRO or deemed to be of comparable quality by the portfolio managers. <br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Fund may invest up to 25% of its total assets in foreign securities. The Fund may also invest in securities, whether or not considered foreign securities, which carry foreign credit exposure. The Fund may also invest up to 15% of its total assets in securities of issuers located in developing markets. <br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In selecting securities for the Fund&#146;s portfolio, the portfolio managers focus on junk bonds that they believe have favorable prospects for high current income and the possibility of growth of capital. Before purchasing securities for the Fund, the portfolio managers conduct a <font style="white-space: nowrap">bottom-up</font> fundamental analysis of an issuer that involves an evaluation by a team of credit analysts of an issuer&#146;s financial condition. The fundamental analysis is supplemented by (i)&#160;an ongoing review of the securities&#146; relative value compared with other junk bonds, and (ii)&#160;a top-down analysis of sector and macro-economic trends. <br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The portfolio managers attempt to control the Fund&#146;s risk by (i)&#160;limiting the portfolio&#146;s assets that are invested in any one security, and (ii)&#160;diversifying the portfolio&#146;s holdings over a number of different industries. The portfolio managers will consider selling a security if (1)&#160;there appears to be deterioration in a security&#146;s risk profile, or (2)&#160;they determine that other securities offer better value. <br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Fund can invest in derivative instruments, specifically forward currency contracts, to mitigate the risk of foreign currency exposure, and credit default swaps and credit default swap indexes, to gain or reduce exposure to an asset class or a particular issuer. <br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A forward currency contract is an agreement between parties to exchange a specified amount of currency at a specified future time at a specified rate. Forward currency contracts are used to protect against uncertainty in the level of future currency exchange rates or to gain or modify exposure to a particular currency. The Fund can use these contracts to hedge against adverse movements in the foreign currencies in which portfolio securities are denominated. <br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A credit default swap is an agreement between two parties where the first party agrees to make one or more payments to the second party, while the second party assumes the risk of certain defaults. The Fund can enter into credit default swaps to create long or short exposure to corporate or sovereign debt securities. The Fund can buy a credit default swap (buy credit protection) or sell a credit default swap (sell credit protection). When the Fund buys a credit default swap it makes a stream of payments based on a fixed interest rate (the premium) over the life of the swap in exchange for a counterparty (the seller) taking on the risk of default of a reference debt obligation. Alternatively, the Fund can sell a credit default swap whereby the Fund can receive premium payments from the buyer in exchange for taking the risk of default of the underlying reference obligation. <br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Fund can invest in credit default swap indices which are credit derivatives used to hedge credit risk or take a position on a basket of credit entities. Credit default swap indices allow an investor to gain or reduce exposure on a basket of credit entities in a more efficient manner than transacting in single name credit default swaps. Unlike a credit default swap, a credit default swap index is a standardized credit security and therefore may be more liquid.-0.3275As with any mutual fund investment, loss of money is a risk of investing. An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency. The risks associated with an investment in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are: <br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Credit Risk</i>. The issuer of instruments in which the Fund invests may be unable to meet interest <font style="white-space: nowrap">and/or</font> principal payments, thereby causing its instruments to decrease in value and lowering the issuer&#146;s credit rating. <br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Derivatives Risk</i>. The performance of derivative instruments is tied to the performance of an underlying currency, security, index or other instrument. In addition to risks relating to their underlying instruments, the use of derivatives may include other, possibly greater, risks. Derivatives involve costs, may be volatile, and may involve a small initial investment relative to the risk assumed. Risks associated with the use of derivatives may include counterparty, leverage, correlation, liquidity, tax, market, interest rate and management risks. Derivatives may also be more difficult to purchase, sell or value than other investments. The Fund may lose more than the cash amount invested on investments in derivatives. Investors should bear in mind that, while the Fund intends to use derivative strategies, it is not obligated to actively engage in these transactions, generally or in any particular kind of derivative, if the investment manager elects not to do so due to availability, cost, market conditions or other factors. <br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Developing/Emerging Markets Securities Risk</i>. Securities issued by foreign companies and governments located in developing/emerging countries may be affected more negatively by inflation, devaluation of their currencies, higher transaction costs, delays in settlement, adverse political developments, the introduction of capital controls, withholding taxes, nationalization of private assets, expropriation, social unrest, war or lack of timely information than those in developed countries. <br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Foreign Securities Risk</i>. The Fund&#146;s foreign investments may be affected by changes in a foreign country&#146;s exchange rates, political and social instability, changes in economic or taxation policies, difficulties when enforcing obligations, decreased liquidity, and increased volatility. Foreign companies may be subject to less regulation resulting in less publicly available information about the companies. <br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>High Yield Bond (Junk Bond) Risk</i>. Junk bonds involve a greater risk of default or price changes due to changes in the credit quality of the issuer. The values of junk bonds fluctuate more than those of high-quality bonds in response to company, political, regulatory or economic developments. Values of junk bonds can decline significantly over short periods of time. <br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Interest Rate Risk</i>. Interest rate risk refers to the risk that bond prices generally fall as interest rates rise; conversely, bond prices generally rise as interest rates fall. Specific bonds differ in their sensitivity to changes in interest rates depending on their individual characteristics, including duration. <br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Management Risk</i>. The investment techniques and risk analysis used by the Fund&#146;s portfolio managers may not produce the desired results. <br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Market Risk</i>. The prices of and the income generated by the Fund&#146;s securities may decline in response to, among other things, investor sentiment, general economic and market conditions, regional or global instability, and currency and interest rate fluctuations. <br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Reinvestment Risk</i>. Reinvestment risk is the risk that a bond&#146;s cash flows (coupon income and principal repayment) will be reinvested at an interest rate below that on the original bond. <br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Synthetic Securities Risk</i>. Fluctuations in the values of synthetic securities may not correlate perfectly with the instruments they are designed to replicate. Synthetic securities may be subject to interest rate changes, market price fluctuations, counterparty risk and liquidity risk.-0.4687As with any mutual fund investment, loss of money is a risk of investing.-0.0399-0.0399-0.0492-0.025-0.0440.0209-0.0165-0.0530.03390.03290.02890.02940.02920.05290.0448After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes.Actual after-tax returns depend on an investor&#8217;s tax situation and may differ from those shown, and after-tax returns shown are not relevant to investors who hold their Fund shares through tax-deferred arrangement, such as 401(k) plans or individual retirement accounts.After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes.Actual after-tax returns depend on an investor&#146;s tax situation and may differ from those shown, and after-tax returns shown are not relevant to investors who hold their Fund shares&#160;through tax-deferred arrangement, such as 401(k) plans or individual retirement accounts.000.00680.0064214205-0.25020.01752009-06-300.2337Worst Quarter2008-12-310.0175-0.0090.01150.01430.07840.04960.02850.07420.04210.04360.0710.05780.08960.0708June&#160;30, 2013<b><font style="font-family: Arial, Helvetica; color: #1E1C77">Investment Objective(s)</font></b><b><font style="font-family: Arial, Helvetica; color: #1E1C77">Fees and Expenses of the Fund</font></b><b><font style="font-family: Arial, Helvetica; color: #1E1C77">Investment Objective(s)</font></b><b><font style="font-family: Arial, Helvetica; color: #1E1C77">Fees and Expenses of the Fund</font></b>000.00550.0043176<b><font style="font-family: Arial, Helvetica; color: #1E1C77">Investment Objective(s)</font></b>138<b>Portfolio Turnover.</b><b><font style="font-family: Arial, Helvetica; color: #1E1C77">Fees and Expenses of the Fund</font></b>00The Fund invests under normal circumstances at least 80% of its net assets (plus any borrowings for investment purposes) in direct obligations of the U.S. Treasury, including bills, notes and bonds.

An interest rate futures contract is an exchange-traded contact in which the specified underlying security is either an interest-bearing fixed income security or an inter-bank deposit. Interest rate futures are based off an underlying security which is a debt obligation and moves in value as interest rates change.<br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Fund intends to maintain an average weighted maturity of three years or less.<br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The portfolio managers utilize an appropriate benchmark index in structuring the portfolio. The portfolio managers then decide on risk factors to use in managing the Fund relative to that benchmark. In doing so, the portfolio managers consider recommendations from a team of independent specialists in positioning the Fund to generate alpha (specific factors affecting the return on investments in excess of the benchmark). The portfolio managers generally rely upon a different team of specialists for trade execution and for assistance in determining the most efficient way (in terms of cost-efficiency and security selection) to implement those recommendations. Although a variety of specialists provide input in the management of the Fund, the portfolio managers retain responsibility for ensuring the Fund is positioned appropriately in terms of risk exposures and position sizes. The portfolio managers rely on the specialists for adjusting the Fund&#146;s risk exposures and security selection. Decisions to purchase or sell securities are determined by the relative value considerations of the investment professionals that factor in economic and credit-related fundamentals, market supply and demand, market dislocations and situation-specific opportunities. The purchase or sale of securities may be related to a decision to alter the Fund&#146;s macro risk exposure (e.g., duration, yield, curve positioning or sector exposure), a need to limit or reduce the Fund&#146;s exposure to a particular security or issuer, degradation of an issuer&#146;s credit quality, or general liquidity needs of the Fund.<br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In attempting to meet its investment objective, the Fund engages in active and frequent trading of portfolio securities.As with any mutual fund investment, loss of money is a risk of investing. An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency. Although the Fund seeks to preserve the value of your investment at $1.00 per share, you may lose money by investing in the Fund. The risks associated with an investment in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are:<br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Cash/Cash Equivalents Risk</i>. Holding cash or cash equivalents may negatively affect performance. <br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Counterparty Risk</i>. Counterparty risk is the risk that the other party to the contract will not fulfill its contractual obligations, which may cause losses or additional costs to the Fund. <br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Credit Risk</i>. The issuer of instruments in which the Fund invests may be unable to meet interest <font style="white-space: nowrap">and/or</font> principal payments, thereby causing its instruments to decrease in value and lowering the issuer&#146;s credit rating. <br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Foreign Securities Risk</i>. The Fund&#146;s foreign investments may be affected by changes in a foreign country&#146;s exchange rates, political and social instability, changes in economic or taxation policies, difficulties when enforcing obligations, decreased liquidity, and increased volatility. Foreign companies may be subject to less regulation resulting in less publicly available information about the companies. <br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Industry Focus Risk</i>. To the extent the Fund invests in securities issued or guaranteed by companies in the banking and financial services industries, the Fund&#146;s performance will depend on the overall condition of those industries, which may be affected by the following factors: the supply of short-term financing, changes in government regulation and interest rates, and overall economy. <br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Interest Rate Risk</i>. Interest rate risk refers to the risk that bond prices generally fall as interest rates rise; conversely, bond prices generally rise as interest rates fall. Specific bonds differ in their sensitivity to changes in interest rates depending on their individual characteristics, including duration. <br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Management Risk</i>. The investment techniques and risk analysis used by the Fund&#146;s portfolio managers may not produce the desired results. <br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Market Risk</i>. The prices of and the income generated by the Fund&#146;s securities may decline in response to, among other things, investor sentiment, general economic and market conditions, regional or global instability, and currency and interest rate fluctuations. <br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Money Market Fund&#160;Risk</i>. Although the Fund seeks to preserve the value of your investment at $1.00 per share, you may lose money by investing in the Fund. The share price of money market funds can fall below the $1.00 share price. You should not rely on or expect the Fund&#146;s adviser or its affiliates to enter into support agreements or take other actions to maintain the Fund&#146;s $1.00 share price. The credit quality of the Fund&#146;s holdings can change rapidly in certain markets, and the default of a single holding could have an adverse impact on the Fund&#146;s share price. The Fund&#146;s share price can also be negatively affected during periods of high redemption pressures <font style="white-space: nowrap">and/or</font> illiquid markets. Further regulation could impact the way the Fund is managed, possibly negatively impacting its return. Additionally, the Fund&#146;s yield will vary as the short-term securities in its portfolio mature or are sold and the proceeds are reinvested in other securities. <br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Municipal Securities Risk</i>. The Fund may invest in municipal securities. Constitutional amendments, legislative enactments, executive orders, administrative regulations, voter initiatives, and the issuer&#146;s regional economic conditions may affect the municipal security&#146;s value, interest payments, repayment of principal and the Fund&#146;s ability to sell it. Failure of a municipal security issuer to comply with applicable tax requirements may make income paid thereon taxable, resulting in a decline in the security&#146;s value. In addition, there could be changes in applicable tax laws or tax treatments that reduce or eliminate the current federal income tax exemption on municipal securities or otherwise adversely affect the current federal or state tax status of municipal securities. <br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Reinvestment Risk</i>. Reinvestment risk is the risk that a bond&#146;s cash flows (coupon income and principal repayment) will be reinvested at an interest rate below that on the original bond. <br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Repurchase Agreement Risk</i>. If the seller of a repurchase agreement in which the Fund invests defaults on its obligation or declares bankruptcy, the Fund may experience delays in selling the securities underlying the repurchase agreement resulting in losses.<br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>U.S.&#160;Government Obligations Risk</i>. The Fund may invest in obligations issued by U.S.&#160;Government agencies and instrumentalities that may receive varying levels of support from the government, which could affect the Fund&#146;s ability to recover should they default.<br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Variable-Rate Demand Notes&#160;Risk</i>. The absence of an active secondary market for certain variable and floating rate notes could make it difficult to dispose of the instruments, and a portfolio could suffer a loss if the issuer defaults during periods in which a portfolio is not entitled to exercise its demand rights.As with any mutual fund investment, loss of money is a risk of investing.As with any mutual fund investment, loss of money is a risk of investing.

The risks associated with an investment in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are:<br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Active Trading Risk</i>. The Fund engages in frequent trading of portfolio securities. Active trading results in added expenses and may result in a lower return and increased tax liability.<br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Derivatives Risk</i>. The performance of derivative instruments is tied to the performance of an underlying currency, security, index or other instrument.

Duration is a measure of volatility expressed in years and represents the anticipated percent change in a bond&#146;s price at a single point in time for a 1% change in yield. As duration increases, volatility increases as applicable interest rates change.<br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The portfolio managers utilize an appropriate benchmark index in structuring the portfolio.

Decisions to purchase or sell securities are determined by the relative value considerations of the investment professionals that factor in economic and credit-related fundamentals, market supply and demand, market dislocations and situation-specific opportunities. The purchase or sale of securities may be related to a decision to alter the Fund&#146;s macro risk exposure (e.g. duration, yield, curve positioning, sector exposure), a need to limit or reduce the Fund&#146;s exposure to a particular security or issuer, degradation of an issuer&#146;s credit quality, or general liquidity needs of the Fund.The Fund invests, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in securities of real estate and real estate-related issuers, including real estate investment trusts (REITs). The Fund invests primarily in equity securities.<br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In complying with the 80% investment requirement, the Fund may include synthetic securities that have economic characteristics similar to the Fund&#146;s direct investments that are counted toward the 80% investment requirement. The Fund may also invest in debt securities including U.S. Treasury and agency bonds and notes.<br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Fund considers an issuer to be a real estate or real estate-related issuer if at least 50% of its assets, gross income or net profits are attributable to ownership, construction, management or sale of residential, commercial or industrial real estate. These issuers include (i)&#160;REITs or other real estate operating issuers that (a)&#160;own property, (b)&#160;make or invest in short term construction and development mortgage loans, or (c)&#160;invest in long-term mortgages or mortgage pools, and (ii)&#160;issuers whose products and services are related to the real estate industry, such as manufacturers and distributors of building supplies and financial institutions that issue or service mortgages.<br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Fund may invest in equity and debt securities of issuers unrelated to the real estate industry that the portfolio managers believe are undervalued and have potential for growth of capital.

A short sale occurs when the Fund sells a security, but does not deliver a security it owns when the sale settles. Instead, it borrows that security for delivery when the sale settles. The Fund may engage in short sales with respect to securities it owns (short sales against the box) or securities it does not own. Generally, the Fund will sell a security short to (1)&#160;take advantage of an expected decline in the security price in anticipation of purchasing the same security at a later date at a lower price, or (2)&#160;to protect a profit in a security that it owns (short sales against the box). The Fund will not sell a security short, if as a result of such short sale, the aggregate market value of all securities sold short exceeds 15% of the Fund&#146;s net assets.<br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;When constructing the portfolio, the portfolio managers use a fundamentals driven investment process, including an evaluation of factors such as real property market cycle analysis, real property evaluation and management and structure review to identify securities with characteristics including (i)&#160;quality underlying properties, (ii)&#160;solid management teams with the ability to effectively manage capital structure decisions, and (iii)&#160;attractive valuations relative to peer investment alternatives.<br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The portfolio managers and investment team focus on equity REITs and real estate operating issuers. Some of the fundamental factors that are evaluated in screening potential investments for the Fund include: forecasted occupancy and rental rates of the various property markets in which a firm may operate, property locations, physical attributes and cash flow generating capacity of an issuer&#146;s properties and calculating relative return potential, asset quality, management depth and skill, insider ownership, overall debt levels, percentage of variable rate financing and fixed charge coverage ratios. The issuers that are believed to have the most attractive fundamental attributes are then screened according to pricing factors that allow the management team to assess security valuations relative to one another and relative to the investment teams&#146; assessment of underlying asset value. The portfolio managers also consider the relative liquidity of each security in the construction of the Fund. <br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The portfolio managers seek to construct a portfolio with risk characteristics similar to the FTSE NAREIT All Equity REITs Index (the benchmark index). The Fund seeks to limit risk through various controls, such as diversifying the portfolio property types and geographic areas as well as by limiting the size of any one holding. Various factors may lead to overweighting or underweighting of particular property types <font style="white-space: nowrap">and/or</font> geographic areas from time to time.<br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The portfolio managers will consider selling a security if they conclude (1)&#160;its relative valuation falls below desired levels, (2)&#160;its risk/return profile changes significantly, (3)&#160;its fundamentals change, or (4)&#160;a more attractive investment opportunity is identified.As with any mutual fund investment, loss of money is a risk of investing. An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency. The risks associated with an investment in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are:<br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Credit Risk</i>. The issuer of instruments in which the Fund invests may be unable to meet interest <font style="white-space: nowrap">and/or</font> principal payments, thereby causing its instruments to decrease in value and lowering the issuer&#146;s credit rating.<br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Derivatives Risk</i>. The performance of derivative instruments is tied to the performance of an underlying currency, security, index or other instrument. In addition to risks relating to their underlying instruments, the use of derivatives may include other, possibly greater, risks. Derivatives involve costs, may be volatile, and may involve a small initial investment relative to the risk assumed. Risks associated with the use of derivatives may include counterparty, leverage, correlation, liquidity, tax, market, interest rate and management risks. Derivatives may also be more difficult to purchase, sell or value than other investments. The Fund may lose more than the cash amount invested on investments in derivatives. Investors should bear in mind that, while the Fund intends to use derivative strategies, it is not obligated to actively engage in these transactions, generally or in any particular kind of derivative, if the investment manager elects not to do so due to availability, cost, market conditions or other factors.<br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Developing/Emerging Markets Securities Risk</i>. Securities issued by foreign companies and governments located in developing/emerging countries may be affected more negatively by inflation, devaluation of their currencies, higher transaction costs, delays in settlement, adverse political developments, the introduction of capital controls, withholding taxes, nationalization of private assets, expropriation, social unrest, war or lack of timely information than those in developed countries.<br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Dollar Roll Transactions Risk</i>. Dollar roll transactions involve the risk that the market value and yield of the securities retained by the Fund may decline below the price of the mortgage-related securities sold by the Fund that it is obligated to repurchase.<br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Foreign Securities Risk</i>. The Fund&#146;s foreign investments may be affected by changes in a foreign country&#146;s exchange rates, political and social instability, changes in economic or taxation policies, difficulties when enforcing obligations, decreased liquidity, and increased volatility. Foreign companies may be subject to less regulation resulting in less publicly available information about the companies.<br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>High Yield Bond (Junk Bond) Risk</i>. Junk bonds involve a greater risk of default or price changes due to changes in the credit quality of the issuer. The values of junk bonds fluctuate more than those of high-quality bonds in response to company, political, regulatory or economic developments. Values of junk bonds can decline significantly over short periods of time.<br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Interest Rate Risk</i>. Interest rate risk refers to the risk that bond prices generally fall as interest rates rise; conversely, bond prices generally rise as interest rates fall. Specific bonds differ in their sensitivity to changes in interest rates depending on their individual characteristics, including duration.<br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Management Risk</i>. The investment techniques and risk analysis used by the Fund&#146;s portfolio managers may not produce the desired results.<br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Market Risk</i>. The prices of and the income generated by the Fund&#146;s securities may decline in response to, among other things, investor sentiment, general economic and market conditions, regional or global instability, and currency and interest rate fluctuations.<br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Mortgage- and Asset-Backed Securities Risk</i>. The Fund may invest in mortgage- and asset-backed securities that are subject to prepayment or call risk, which is the risk that the borrower&#146;s payments may be received earlier or later than expected due to changes in prepayment rates on underlying loans. Faster prepayments often happen when interest rates are falling. As a result, the Fund may reinvest these early payments at lower interest rates, thereby reducing the Fund&#146;s income. Conversely, when interest rates rise, prepayments may happen more slowly, causing the security to lengthen in duration. Longer duration securities tend to be more volatile. Securities may be prepaid at a price less than the original purchase value. An unexpectedly high rate of defaults on the mortgages held by a mortgage pool may adversely affect the value of mortgage-backed securities and could result in losses to the Fund. The risk of such defaults is generally higher in the case of mortgage pools that include subprime mortgages. Subprime mortgages refer to loans made to borrowers with weakened credit histories or with lower capacity to make timely payments on their mortgages.<br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Reinvestment Risk</i>. Reinvestment risk is the risk that a bond&#146;s cash flows (coupon income and principal repayment) will be reinvested at an interest rate below that on the original bond.<br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Synthetic Securities Risk</i>. Fluctuations in the values of synthetic securities may not correlate perfectly with the instruments they are designed to replicate. Synthetic securities may be subject to interest rate changes, market price fluctuations, counterparty risk and liquidity risk.<br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>U.S.&#160;Government Obligations Risk</i>. The Fund may invest in obligations issued by U.S.&#160;Government agencies and instrumentalities that may receive varying levels of support from the government, which could affect the Fund&#146;s ability to recover should they default.-0.04510.01122009-06-300.0323Worst Quarter2008-09-30As with any mutual fund investment, loss of money is a risk of investing.The Fund invests only in the following high-quality U.S. dollar-denominated short-term debt obligations: (i)&#160;securities issued by the U.S. Government or its agencies; (ii)&#160;bankers&#146; acceptances, certificates of deposit, and time deposits from U.S. or foreign banks; (iii)&#160;repurchase agreements; (iv)&#160;commercial paper; (v)&#160;municipal securities; (vi)&#160;master notes; and (vii)&#160;cash equivalents. <br /><br />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The Fund will limit investments to those securities that are First Tier&#160;Securities (defined below) at the time of purchase. <br /><br />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; As permitted by <font style="white-space: nowrap">Rule&#160;2a-7</font> under the Investment Company Act of 1940 <font style="white-space: nowrap">(&#147;Rule&#160;2a-7&#148;),</font> the Fund seeks to maintain a stable price of $1.00 per share by using the amortized cost method to value portfolio securities and rounding the share value to the nearest cent. The Fund invests in conformity with SEC rules and regulations requirements for money market funds for the quality, maturity, diversification and liquidity of investments. The Fund invests only in U.S. dollar-denominated securities maturing within 397&#160;days of the date of purchase, with certain exceptions permitted by applicable regulations. The Fund maintains a dollar-weighted average portfolio maturity of no more than 60&#160;days, and a dollar-weighted average portfolio maturity as determined without exceptions regarding certain interest rate adjustments under <font style="white-space: nowrap">Rule&#160;2a-7</font> of no more than 120&#160;days. Each investment must be determined to present minimal credit risks by the Fund&#146;s Adviser pursuant to guidelines approved by the Fund&#146;s Board of Trustees, and must be an &#147;Eligible Security&#148; as defined under applicable regulations. First Tier&#160;Securities generally means Eligible Securities rated within the highest short-term rating category, unrated securities of comparable quality as determined by the Adviser under the supervision of the Board of Trustees, U.S. Government Securities as defined by applicable regulations, and securities issued by other registered money market funds. <br /><br />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The Fund may invest up to 50% of its assets in U.S. dollar-denominated foreign securities. The Fund may also invest in securities, whether or not considered foreign securities, which carry foreign credit exposure. <br /><br />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; In selecting securities for the Fund&#146;s portfolio, the portfolio managers focus on safety, liquidity, and a competitive yield. The Adviser conducts a credit analysis of each potential issuer prior to the purchase of its securities. <br /><br />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The portfolio managers normally hold portfolio securities to maturity, but may sell a particular security when they deem it advisable, such as when market or credit factors materially change.After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes.Actual after-tax returns depend on an investor&#146;s tax situation and may differ from those shown, and after-tax returns shown are not relevant to investors who hold their Fund shares&#160;through tax-deferred arrangement, such as 401(k) plans or individual retirement accounts.2009-09-300.3216Worst Quarter2008-12-310.00020.01120.00240.00730.00620.07840.01590.0154<b><font style="font-family: Arial, Helvetica; color: #1E1C77">Investment Objective(s)</font></b>00.0048154<b>Portfolio Turnover.</b><b><font style="font-family: Arial, Helvetica; color: #1E1C77">Principal Investment Strategies of the Fund</font></b>0.0805The Fund invests under normal circumstances at least 80% of its net assets (plus any borrowings for investment purposes) in debt securities issued, guaranteed or otherwise backed by the U.S. Government or its agencies and instrumentalities. These securities include: (1)&#160;U.S. Treasury obligations and (2)&#160;obligations issued or guaranteed by U.S. Government agencies and instrumentalities and supported by (a)&#160;the full faith and credit of the U.S. Treasury, (b)&#160;the right of the issuer to borrow from the U.S. Treasury, or (c)&#160;the credit of the agency or instrumentality. The principal type of fixed income securities purchased by the Fund are callable bonds that can be redeemed by the issuer prior to their stated maturity, bullet-maturity debt bonds with a stated maturity date; mortgage-backed securities (MBS) consisting of interests in underlying mortgages with maturities of up to thirty years, and Treasury and agency holdings. The Fund may also invest in derivative instruments such as treasury futures and options on treasury futures. The Fund may enter into reverse repurchase agreements. The Fund often uses Treasury futures and dollar rolls transactions to gain exposure to the Treasury and agency MBS markets while deploying Fund assets in other securities.<br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In complying with the 80% investment requirement, the Fund may include synthetic securities that have economic characteristics similar to the Fund&#146;s direct investments that are counted toward the 80% investment requirement.<br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Fund invests in securities of all maturities, but will maintain a weighted average effective maturity for the portfolio of between three and ten years. <br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Fund may utilize derivative instruments, specifically futures contracts. The Fund will invest in futures contracts to seek exposure to certain asset classes. A futures contract is a standardized agreement between two parties to buy or sell a specific quantity of an underlying instrument at a specific price at a specific future time. The value of the futures contract tends to increase and decrease in tandem with the value of the underlying instrument. Futures contracts are bilateral agreements, with both the purchaser and the seller equally obligated to complete the transaction. Depending on the terms of the particular contract, futures contracts are settled through purchasing an offsetting contract, by physical delivery of the underlying instrument on the settlement date or by payment of a cash settlement amount on the settlement date. <br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The portfolio managers utilize an appropriate benchmark index in structuring the portfolio. The portfolio managers then decide on risk factors to use in managing the Fund relative to that benchmark. In doing so, the portfolio managers consider recommendations from a team of independent specialists in positioning the Fund to generate alpha (specific factors affecting the return on investments in excess of the benchmark). The portfolio managers generally rely upon a different team of specialists for trade execution and for assistance in determining the most efficient way (in terms of cost-efficiency and selection) to implement those recommendations. Although a variety of specialists provide input in the management of the Fund, the portfolio managers retain responsibility for ensuring the Fund is positioned appropriately in terms of risk exposures and position sizes. The portfolio managers rely on the specialists for adjusting the Fund&#146;s risk exposures and security selection. Decisions to purchase or sell securities are determined by the relative value considerations of the investment professionals that factor in economic and credit-related fundamentals, market supply and demand, market dislocations and situation-specific opportunities. The purchase or sale of securities may be related to a decision to alter the fund&#146;s macro risk exposure (e.g. duration, yield, curve positioning, sector exposure), a need to limit or reduce the fund&#146;s exposure to a particular security or issuer, degradation of an issuer&#146;s credit quality, or general liquidity needs of the fund. <br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In attempting to meet its investment objective, the Fund engages in active and frequent trading of portfolio securities.-0.3613June&#160;30, 20130.11910.10220.09860.1150.02920.1020.0922As with any mutual fund investment, loss of money is a risk of investing. An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency. The risks associated with an investment in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are: <br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Active Trading Risk</i>. The Fund engages in frequent trading of portfolio securities. Active trading results in added expenses and may result in a lower return and increased tax liability. <br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Derivatives Risk</i>. The performance of derivative instruments is tied to the performance of an underlying currency, security, index or other instrument. In addition to risks relating to their underlying instruments, the use of derivatives may include other, possibly greater, risks. Derivatives involve costs, may be volatile, and may involve a small initial investment relative to the risk assumed. Risks associated with the use of derivatives may include counterparty, leverage, correlation, liquidity, tax, market, interest rate and management risks. Derivatives may also be more difficult to purchase, sell or value than other investments. The Fund may lose more than the cash amount invested on investments in derivatives. Investors should bear in mind that, while the Fund intends to use derivative strategies, it is not obligated to actively engage in these transactions, generally or in any particular kind of derivative, if the investment manager elects not to do so due to availability, cost, market conditions or other factors. <br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Dollar Roll Transactions Risk</i>. Dollar roll transactions involve the risk that the market value and yield of the securities retained by the Fund may decline below the price of the mortgage-related securities sold by the Fund that it is obligated to repurchase. <br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Interest Rate Risk</i>. Interest rate risk refers to the risk that bond prices generally fall as interest rates rise; conversely, bond prices generally rise as interest rates fall. Specific bonds differ in their sensitivity to changes in interest rates depending on their individual characteristics, including duration. <br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Management Risk</i>. The investment techniques and risk analysis used by the Fund&#146;s portfolio managers may not produce the desired results. <br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Market Risk</i>. The prices of and the income generated by the Fund&#146;s securities may decline in response to, among other things, investor sentiment, general economic and market conditions, regional or global instability, and currency and interest rate fluctuations. <br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Mortgage- and Asset-Backed Securities Risk</i>.

Reverse repurchase agreements involve the risk that the market value of securities to be repurchased may decline below the repurchase price or that the other party may default on its obligation, resulting in delays, additional costs or the restriction of proceeds from the sale. <br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Synthetic Securities Risk</i>. Fluctuations in the values of synthetic securities may not correlate perfectly with the instruments they are designed to replicate. Synthetic securities may be subject to interest rate changes, market price fluctuations, counterparty risk and liquidity risk. <br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>U.S.&#160;Government Obligations Risk</i>. The Fund may invest in obligations issued by U.S.&#160;Government agencies and instrumentalities that may receive varying levels of support from the government, which could affect the Fund&#146;s ability to recover should they default.As with any mutual fund investment, loss of money is a risk of investing.As with any mutual fund investment, loss of money is a risk of investing.0.12160.0783<b><font style="font-family: Arial, Helvetica; color: #1E1C77">Investment Objective(s)</font></b><b><font style="font-family: Arial, Helvetica; color: #1E1C77">Fees and Expenses of the Fund</font></b>After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes.Actual after-tax returns depend on an investor&#146;s tax situation and may differ from those shown, and after-tax returns shown are not relevant to investors who hold their Fund shares&#160;through tax-deferred arrangement, such as 401(k) plans or individual retirement accounts.000.00470.00472008-12-310.0734Worst Quarter2010-12-310.05150.03390.03330.05780.05590.0534151151<b>Portfolio Turnover.</b><b><font style="font-family: Arial, Helvetica; color: #1E1C77">Principal Investment Strategies of the Fund</font></b>The Fund&#146;s investment adviser, Invesco Advisers, Inc. (the Adviser), seeks to achieve the Fund&#146;s investment objectives by investing primarily in a portfolio of corporate debt securities. The Fund invests, under normal circumstances, at least 80% of its net assets at the time of investment (plus any borrowings for investment purposes) in corporate bonds. For these purposes a corporate bond is defined as any corporate debt security with an original term to maturity of greater than one year.<br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Fund utilizes active duration and yield curve positioning for risk management and for generating alpha versus its benchmark. Duration is a measure of volatility expressed in years and represents the anticipated percent change in a bond&#146;s price at a single point in time for a 1% change in yield. As duration increases, volatility increases as applicable interest rates change.<br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The portfolio managers utilize an appropriate benchmark index in structuring the portfolio. The portfolio managers decide on appropriate risk factors such as sector and issuer weightings and duration relative to that benchmark. The portfolio managers then employ proprietary technology to calculate appropriate position sizes for each of these risk factors. In doing so, the portfolio managers consider recommendations from a globally interconnected team of specialist decision makers in positioning the Fund to generate alpha (specific factors affecting the return on investments in excess of the benchmark).<br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The portfolio managers generally rely upon a team of market-specific specialists for trade execution and for assistance in determining the most efficient way (in terms of cost-efficiency and security selection) to implement those recommendations. Although a variety of specialists provide input in the management of the Fund, the portfolio managers retain responsibility for ensuring the Fund is positioned appropriately in terms of risk exposures and position sizes.<br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Specialist decision makers employ a <font style="white-space: nowrap">bottom-up</font> approach to recommend larger or smaller exposure to specific risk factors. In general, specialists will look for attractive risk-reward opportunities and securities that best enable the Fund to pursue those opportunities. The portfolio managers rely on these decision makers and market specific specialists for adjusting the Fund&#146;s risk exposures and security selection on a real-time basis using proprietary communication technology. Portfolio managers retain discretion for deciding how risk positions are implemented. Investment professionals that factor in economic and credit-related fundamentals, market supply and demand, market dislocations and situation-specific opportunities decide to purchase or sell securities using their relative value considerations. The purchase or sale of securities may be related to a decision to alter the Fund&#146;s macro risk exposure (e.g. duration, yield, curve positioning, sector exposure), a need to limit or reduce the Fund&#146;s exposure to a particular security or issuer, degradation of an issuer&#146;s credit quality, or general liquidity needs of the Fund.<br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Types of Securities.</i> Under normal market conditions, the Fund invests primarily in corporate debt securities with original maturities of more than one year. The Fund may invest up to 20% of its total assets in convertible securities and up to 10% of its total assets in preferred stocks. In addition, a portion or all of the Fund&#146;s total assets may be invested in securities issued by foreign governments or corporations; provided, however, that the Fund may not invest more than 30% of its total assets in <font style="white-space: nowrap">non-U.S.</font> dollar denominated securities. Debt securities purchased by the Fund may include issuer call provisions. The Fund may from time to time invest in derivative instruments such as futures contracts and swap agreements, including but not limited to interest rate futures, credit default swaps, and engage in mortgage dollar roll transactions, a form of repurchase agreement activity in the to-be-announced (TBA) market for agency mortgage-backed securities (MBS). These strategies are implemented within the risk profile of the guidelines set forth in the prospectus. The Fund may engage in dollar roll transactions to enhance the Fund&#146;s return on cash.<br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Quality Levels.</i> Under normal market conditions, between 60% to 100% of the Fund&#146;s total assets are invested in investment grade securities, which are securities rated Baa or higher by Moody&#146;s Investors Service, Inc. (Moody&#146;s) or BBB or higher by Standard&#160;&#038; Poor&#146;s (S&#038;P) at the time they are purchased, securities issued or guaranteed by the U.S. government, its agencies or instrumentalities, commercial paper rated Prime by Moody&#146;s or A by S&#038;P and cash and cash equivalents.<br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Up to 40% of the Fund&#146;s total assets may be invested in securities rated Ba by Moody&#146;s or BB by S&#038;P at the time of purchase. No more than 20% of the Fund&#146;s total assets may be invested in securities rated B or lower by Moody&#146;s or S&#038;P, or which are unrated, although it is the Fund&#146;s current policy not to buy any securities rated below B or unrated securities judged by the Adviser to be of comparable quality. Securities rated Ba or lower by Moody&#146;s or BB or lower by S&#038;P or unrated securities of comparable quality are commonly referred to as junk bonds and involve greater risks than investments in higher-grade securities.As with any mutual fund investment, loss of money is a risk of investing. An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The risks associated with an investment in the Fund can increase during times of significant market volatility. The principle risks of investing in the Fund are:<br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Credit Risk.</i> The issuer of instruments in which the Fund invests may be unable to meet interest <font style="white-space: nowrap">and/or</font> principal payments, thereby causing its instruments to decrease in value and lowering the issuer&#146;s credit rating.<br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Market Risk.</i> The prices of and the income generated by the Fund&#146;s securities may decline in response to, among other things, investor sentiment; general economic and market conditions; regional or global instability; and currency and interest rate fluctuations.<br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Interest Rate Risk.</i> Interest rate risk refers to the risk that bond prices generally fall as interest rates rise; conversely, bond prices generally rise as interest rates fall. Specific bonds differ in their sensitivity to changes in interest rates depending on their individual characteristics, including duration.<br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Management Risk.</i> The investment techniques and risk analysis used by the Fund&#146;s portfolio managers may not produce the desired results.<br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Income Risk.</i> The income you receive from the Fund is based primarily on prevailing interest rates, which can vary widely over the short- and long-term. If interest rates drop, your income from the Fund may drop as well.<br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Preferred Securities Risk.</i> There are special risks associated with investing in preferred securities. Preferred securities may include provisions that permit the issuer, in its discretion, to defer or omit distributions for a certain period of time. If the Fund owns a security that is deferring or omitting its distributions, the Fund may be required to report the distribution on its tax returns, even though it may not have received this income. Further, preferred securities may lose substantial value due to the omission or deferment of dividend payments.<br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Call Risk.</i> If interest rates fall, it is possible that issuers of debt securities with high interest rates will prepay or call their securities before their maturity dates. In this event, the proceeds from the called securities would likely be reinvested by the Fund in securities bearing the new, lower interest rates, resulting in a possible decline in the Fund&#146;s income and distributions to shareholders.<br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Foreign Securities Risk.</i> The Fund&#146;s foreign investments may be affected by changes in a foreign country&#146;s exchange rates; political and social instability; changes in economic or taxation policies; difficulties when enforcing obligations; decreased liquidity; and increased volatility. Foreign companies may be subject to less regulation resulting in less publicly available information about the companies.<br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Derivatives Risk.</i> The performance of derivative instruments is tied to the performance of an underlying currency, security, index or other instrument. In addition to risks relating to their underlying instruments, the use of derivatives may include other, possibly greater, risks. Derivatives involve costs, may be volatile, and may involve a small initial investment relative to the risk assumed. Risks associated with the use of derivatives include counterparty, leverage, correlation, liquidity, tax, market, interest rate and management risks. Derivatives may also be more difficult to purchase, sell or value than other investments. The Fund may lose more than the cash amount invested on investments in derivatives.<br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Investors should bear in mind that, while the Fund intends to use derivative strategies, it is not obligated to actively engage in these transactions, generally or in any particular kind of derivative, if the investment manager elects not to do so due to availability, cost, market conditions or other factors.<br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Developing /Emerging Markets Securities Risk.</i> Securities issued by foreign companies and governments located in developing/emerging countries may be affected more negatively by inflation, devaluation of their currencies, higher transaction costs, delays in settlement, adverse political developments, the introduction of capital controls, withholding taxes, nationalization of private assets, expropriation, social unrest, war or lack of timely information than those in developed countries.<br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Dollar Roll Transaction Risk.</i> Dollar roll transactions involve the risk that the market value and yield of the securities retained by the Fund may decline below the price of the mortgage-related securities sold by the Fund that it is obligated to repurchase.<br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Convertible Securities Risk.</i> The Fund may own convertible securities, the value of which may be affected by market interest rates, the risk that the issuer will default, the value of the underlying stock or the right of the issuer to buy back the convertible securities.<br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>High Yield Bond (Junk Bond) Risk.</i> Junk bonds involve a greater risk of default or price changes due to changes in the credit quality of the issuer. The values of junk bonds fluctuate more than those of high-quality bonds in response to company, political, regulatory or economic developments. Values of junk bonds can decline significantly over short periods of time.As with any mutual fund investment, loss of money is a risk of investing.After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes.Actual after-tax returns depend on an investor&#146;s tax situation and may differ from those shown, and after-tax returns shown are not relevant to investors who hold their Fund shares&#160;through tax-deferred arrangement, such as 401(k) plans or individual retirement accounts.0.06442011-12-310.0212Worst Quarter2011-09-30As with any mutual fund investment, loss of money is a risk of investing. An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency. The risks associated with an investment in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are: <br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Concentration Risk</i>. To the extent the Fund invests a greater amount in any one sector or industry, the Fund&#146;s performance will depend to a greater extent on the overall condition of the sector or industry, and there is increased risk to the Fund if conditions adversely affect that sector or industry.<br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Credit Risk</i>. The issuer of instruments in which the Fund invests may be unable to meet interest <font style="white-space: nowrap">and/or</font> principal payments, thereby causing its instruments to decrease in value and lowering the issuer&#146;s credit rating. <br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>High Yield Bond (Junk Bond) Risk</i>. Junk bonds involve a greater risk of default or price changes due to changes in the credit quality of the issuer. The values of junk bonds fluctuate more than those of high-quality bonds in response to company, political, regulatory or economic developments. Values of junk bonds can decline significantly over short periods of time.<br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Interest Rate Risk</i>. Interest rate risk refers to the risk that bond prices generally fall as interest rates rise; conversely, bond prices generally rise as interest rates fall. Specific bonds differ in their sensitivity to changes in interest rates depending on their individual characteristics, including duration.<br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Management Risk</i>. The investment techniques and risk analysis used by the Fund&#146;s portfolio managers may not produce the desired results.<br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Market Risk</i>. The prices of and the income generated by the Fund&#146;s securities may decline in response to, among other things, investor sentiment, general economic and market conditions, regional or global instability, and currency and interest rate fluctuations.<br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>REIT Risk/Real Estate Risk</i>. Investments in real estate related instruments may be affected by economic, legal, cultural, environmental or technological factors that affect property values, rents or occupancies of real estate related to the Fund&#146;s holdings. Real estate companies, including REITs or similar structures, tend to be small and mid cap companies, and their shares may be more volatile and less liquid. The value of investments in real estate related companies may be affected by the quality of management, the ability to repay loans, the utilization of leverage and financial covenants related thereto, whether the company carries adequate insurance and environmental factors. If a real estate related company defaults, the Fund may own real estate directly, which involves the following additional risks: environmental liabilities, difficulty in valuing and selling the real estate, and economic or regulatory changes.<br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Short Sales Risk</i>. Short sales may cause the Fund to repurchase a security at a higher price, causing a loss. As there is no limit on how much the price of the security can increase, the Fund&#146;s exposure is unlimited.<br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>Synthetic Securities Risk</i>. Fluctuations in the values of synthetic securities may not correlate perfectly with the instruments they are designed to replicate. Synthetic securities may be subject to interest rate changes, market price fluctuations, counterparty risk and liquidity risk.<br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i>U.S.&#160;Government Obligations Risk</i>. The Fund may invest in obligations issued by U.S.&#160;Government agencies and instrumentalities that may receive varying levels of support from the government, which could affect the Fund&#146;s ability to recover should they default.0.05520.03560.0360.06350.05440.06080.0636After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes.Actual after-tax returns depend on an investor&#146;s tax situation and may differ from those shown, and after-tax returns shown are not relevant to investors who hold their Fund shares&#160;through tax-deferred arrangement, such as 401(k) plans or individual retirement accounts.After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes.Actual after-tax returns depend on an investor&#146;s tax situation and may differ from those shown, and after-tax returns shown are not relevant to investors who hold their Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.<b><font style="font-family: Arial, Helvetica; color: #1E1C77">Fees and Expenses of the Fund</font>2012-09-212012-09-242012-09-24falseThe Fund&#8217;s investment objective is long-term growth of capital.The Fund&#8217;s investment objective is total return through growth of capital and current income.0.00560.0056000.00160.00060.54<b><font style="font-family: Arial, Helvetica; color: #1E1C77">Principal Risks of Investing in the Fund</font></b>An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency.<b><font style="font-family: Arial, Helvetica; color: #1E1C77">Performance Information</font></b>The bar chart and performance table provide an indication of the risks of investing in the Fund.
